SPECIFICATION forming part of Letters Patent No. 566,212, dated August18, 1896. Application filed April 6, 1896. Serial No. 586,387. (Nomodel.)

To all whom it may concern:

Be it known that I, GEORGE W. MOORE, of Waco, McLennan county, Texas,have invented certain new and useful Improvements in VaginalPowder-Injectors, of which the following is a full, clear, and exactdescrip tion, reference being had to the accompanying drawings, forminga part hereof.

My invention relates to ejectors, and more particularly to ejectors forapplying powder for medicinal purposes to afflicted parts of the bodywithout difficulty.

The invention consists in certain novel and peculiar features ofconstruction and combinations of parts, as will be hereinafter describedand claimed.

In order that the invention may be fully understood, I will proceed todescribe it with reference to the accompanying drawings, wherein Figure1 represents a longitudinal section of the ejector with its operativeparts in the relative positions they occupy before the cup or magazineis charged with powder or before the charge of powder within the cup isejected. Fig. 2 represents a similar view of the cup or magazinewithdrawn in order that as it is again moved forward it may be chargedwith powder. Fig. 3 is a cross-sec tion of the ejector, taken at theinner end of the magazine or cup. Fig. 4c is a detail perspective viewof the cup or magazine.

In said drawings, 1 designates a barrel or cylinder provided with arounded front end 2 and with a hole or passage 3 in said rounded end andin alinement with the longitudinal axis of the barrel or cylinder. Theopposite end ,of the barrel or cylinder is provided with an annularexternal shoulder 4, with a screw-threaded extension engaged by thescrew-cap 5, which closes the inner end of the barrel or cylinder,except that it is provided with a central hole or perforation 6, throughwhich the plunger 7 extends. Said plunger is provided at one end with ahandle 8 and at its opposite end with a head or enlargement 9.

1O designates a cylindrical cup or magazine of such internal diameterthat the head or enlargement of the plunger fits snugly therein, and atits inner end saidmagazine or cup is provided with inwardly-projectingflange or shoulder 11, against which the head of the plunger comes incontact when the same is retracted as far as possible. Said magazine orcup is maintained centrally within the barrel or cylinder by means of anumber of arms 12, which project outwardly from the same and bearagainst the inner surface of said barrel or cylinder, as shown mostclearly in Fig. 3. Said barrel or cylinder is normally held in theposition shown in Fig. 1, that is, with the discharge end of themagazine or cup adjacent to the opening or passage 3 in the rounded orfront end of the barrel or cylinder, by means of the spiral expansivespring 13, which encircles the rod 7 and bears at its opposite endsagainst the screw-cap 5 and the opposing or inner end of the magazine orcup, as clearly shown. In order to charge this magazine or cup withpowder with which it is at all times sur rounded, owing to the fact thatthe barrel or cylinder is filled with the same, an operator first graspsthe handle 8 and withdraws the same from the position shown in Fig. 1 tothe position shown in Fig. 2, holding it also with the rounded or frontend disposed downwardly and one finger across the discharge opening orpassage 3 to prevent the escape of powder therethrough. By thuswithdrawing said magazine or cup it is obvious that, by reason of thediminished diameter of the same relative to the internal diameter of thebarrel or magazine, the powder in the rear or inner end of the cylinderpasses freely through the grooves formed by and between the ribs 12 downto the lower end of the barrel or cylinder and in advance of thewithdrawn magazine or cup. The handle is now released and the pressureof the spring forces the magazine or cup back to its original positionand causes thereby a charge or load of powder to enter and fill saidmagazine or cup, as will be readily understood. The ejector may now bearranged in the proper position relative to the afiiicted part of thebody and the powder within the cylinder or cup discharged by pressinginwardly upon the handle 8 and thereby forcing the head of the same toor near the discharge or front end of the barrel or cylinder. Thisoperation is performed quickly, so that the powder is ejected with acorresponding degree of force.

When the magazine or cup occupies its normal or inoperative position(shown in Fig. l) and is not charged or loaded, its front end registerswith the hole or passage 3, and, bearing against the end of the barrelor cylinder, prevents the accidental escape or spilling from the same ofthe powder, as will be readily understood.

From the above description it is apparent that I have produced apowder-ejector which combines in a high degree efficiency of operationwith simplicity, durability, and inexpensiveness of manufacture.

Having thus described myinvention, what I claim as new, and desire tosecure by Letters Patent, is

1. An ejector comprising a barrel or cylinder having an opening at itsfront end, a magazine or cup arranged within and of less diameter thanthe same, a plunger connected to said magazine or cup and adapted whenwithdrawn a suitable distance to withdraw said magazine or cup from thefront toward the rear end of the barrel or cylinder, and an expansivespring within the barrel or cylinder and exerting pressure against therear or inner end of the magazine or cup, substantially as and for thepurpose set forth.

2. An ejector, comprising a barrel or cylinder provided with an openingin its front end, a cap closing the opposite end of the barrel orcylinder, a cylindrical magazine or cup arranged axially within saidbarrel or cylinder and provided with outwardly-projecting ribs or armswhich bear against the inner surface of the barrel or cylinder, andprovided also at its inner end with a flange or shoulder which projectsinwardly of the interior wall of the magazine or cup, a plungerextending axially of the barrel or cylinder through the cap at its rearend and projecting into said magazine or cup, and provided with a heador enlargement within the same of greater diameter than the openingformed by said inwardlyprojecting flange or shoulder, whereby when theplunger is withdrawn, the magazine or cup is caused to move rearwardlyin the barrel or cylinder with it by reason of said head or enlargementabutting against the said flange or shoulder, and a spring spirallyencircling said plunger and bearing at its opposite ends against thesaid cap and the opposing end of the magazine or cup, substantially asde scribed.

3. An ejector, comprising a barrel or cylinder provided with a roundedfront end having a central opening or passage, a screw-cap closing theopposite end of the barrel or cyl inder, a cylindrical magazine or cuparranged axially within said barrel or cylinder and provided withoutwardly-projeeting ribs or arms which bear against the inner surfaceof the barrel or cylinder, and provided also at its inner end with aflan go or shoulder which proj ects inwardly of the internal wall of themagazine or cup, a plunger having a handle at its rear or outer end,extending axially of the barrel or cylinder through the cap at its rearend and projecting into said magazine or cup and provided with a head orenlargement fitting slidingly within the same of greater diameter thanthe opening formed by said inwardly-projecting flange or shoulder,whereby when the plunger is withdrawn, the magazine or cup then iscaused to move rearwardly in the barrel or cylinder with the plunger byreason of said head or enlargement abutting against the said flange orshoulder, and a spring spirally encircling said plunger and bearing atits opposite ends against the said cap and the opposing end of themagazine or cup, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE lV. MOORE.
